Answer:
- domain: all real numbers
- range: y ≥ 0
Step-by-step explanation:
The domain is the horizontal extent of the graph. For a graph like this, we assume the ends extend to infinity, both horizontally and vertically. Then the horizontal extent (domain) is from -infinity to +infinity: all real numbers.
The graph does not go below y=0, so the vertical extent (range) is y ≥ 0.
Here is what I got:

Answer: 3/8
Explanation: To subtract unlike fractions such as 5/8 - 1/4, first find a common denominator. The common denominator of 8 and 4 will be the least common multiple of 8 and 4 which is 8.
Notice that our first fraction already has 8 in the denominator so it stays the same. To get 8 in the denominator of 1/4, we multiply the numerator and denominator by 2 to get 2/8.
Now we have 5/8 - 2/8.
To subtract like fractions, we simply subtract the numerators to get 3 and keep our denominator of 8 and we have 3/8.
Since 3/8 is in lowest terms, it's our final answer.
Therefore, 5/8 - 1/4 = 3/8.
